Let's divide 2798850 by 620
We want to divide 2798850 by 620.

Advancing to step 1:
If we divide 2 by 620, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 620

Advancing to step 2:
If we divide 27 by 620, we get 0 and a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 620

Going ahead to step 3:
620 can be fit into 279 0 times, resulting in a remainder of 279.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 279 after subtracting 0 from 279.
Fetch the next digit (8) from the dividend, attach it to 279 and continue: 2798 / 620

On to step 4:
620 can be fit into 2798 4 times, resulting in a remainder of 318.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 318 after subtracting 2480 from 2798.
Grab the next digit (8) from the dividend, add it to 318, then carry on: 3188 / 620

On to step 5:
3188 divided by 620 is 5 with a remainder of 88.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 3100 from 3188 leaves us with 88.
Fetch the next digit (5) from the dividend, attach it to 88 and continue: 885 / 620

Moving on to step 6:
620 can be fit into 885 1 times, resulting in a remainder of 265.
Write down 1 as next digit of the result. 
Result so far: 451.0
Subtract 620 from 885 to get 265.
Fetch the next digit (0) from the dividend, attach it to 265 and continue: 2650 / 620

On to step 7:
620 goes into 2650 4 times with a remainder of 170.
The next digit of our result is 4. 
Result so far: 4514.0
The remainder is 170 after subtracting 2480 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 8:
The number 620 fits into 1700 2 times, leaving a remainder of 460.
Record the quotient 2 as the next digit in the result. 
Result so far: 4514.2
Deduct 1240 from 1700 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 9:
The number 620 fits into 4600 7 times, leaving a remainder of 260.
The number 7 becomes the next digit in our result. 
Result so far: 4514.27
Subtracting 4340 from 4600 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 10:
When dividing 2600 by 620, we get 4 with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 4514.274
If we subtract 2480 from 2600, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
If we divide 1200 by 620, we get 1 and a remainder of 580.
Use 1 as the next digit of our solution. 
Result so far: 4514.2741
Deduct 620 from 1200 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 12:
620 can be fit into 5800 9 times, resulting in a remainder of 220.
Use 9 as the next digit of our solution. 
Result so far: 4514.27419
If we subtract 5580 from 5800, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 13:
620 goes into 2200 3 times with a remainder of 340.
The next digit of our result is 3. 
Result so far: 4514.274193
Subtract 1860 from 2200 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 14:
When dividing 3400 by 620, we get 5 with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 4514.2741935
Subtract 3100 from 3400 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 15:
If we divide 3000 by 620, we get 4 and a remainder of 520.
Record the quotient 4 as the next digit in the result. 
Result so far: 4514.27419354
Subtracting 2480 from 3000 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

The final result is 4514.27419354 with a remainder of 5.2e-07.
